Abstract:
Objective: To investigate the chemical constituents of Gracilaria lemaneiformis. Methods: Compounds were isolated by normal phase silica gel and Sephadex LH-20 gel column chromatography. Their structures were elucidated by analyses of spectroscopic data. Results: Nine compounds were isolated from the ethanol extract of G. lemaneiformis, their structures were elucidated as palmitic acid (1), 1, 3-dipalmitin (2), 1-monopalmitin (3), uracil (4), adenosine (5), 2α-oxa-2-oxo-5α-hydroxy-3,4-dinorcholestane (6), 1-O-β-D-galactosyl-(6→1)-α-D-galactosyl-2, 3-O-dihexadecanoyl- glycerol (7), 1-O-α-D-glucose-2, 3-O-dihexadecanoyl-glycerol (8), and β-sitosterol (9). Conclusion: All of these compounds are obtained from this plant for the first time.
